C# 如何获取月份名称 使用（DataAccessAdapter=new DataAccessAdapter（）） { LinqMetaData meta=新的LinqMetaData（适配器）； var数据=（来自meta.Table中的x 其中x.DateCreated>=startDate&&x.DateCreated 0&&x.Cancelled 按新的{month=x.DateCreated.Value.month}将x分组到g中 选择新的 { MonthNr=g.键， //MonthName=？ TotalMonthAmount=g.Sum（x=>x.Amount） }); ..... }

和

startDate

和

endDate

是有效日期

我只得到月号，如何得到创建日期的月名？

new{month=x.DateCreated.Value.month.ToString（“MMM”）}

new{month=x.DateCreated.Value.month.ToString（“MMM”）}

我想你是在问month属性。选中此项：

    using (DataAccessAdapter adapter = new DataAccessAdapter())
       {
         LinqMetaData meta = new LinqMetaData(adapter);
         var datas = (from x in meta.Table
           where x.DateCreated >= startDate && x.DateCreated <= endDate && x.ViaTo > 0 && !x.Cancelled
           group x by new { month = x.DateCreated.Value.Month } into g
           select new
           {
            MonthNr = g.Key,
            //MonthName = ?
            TotalMonthAmount = g.Sum(x => x.Amount)
            });
.....
       }

我想你是在问关于月财产的事。选中此项：

    using (DataAccessAdapter adapter = new DataAccessAdapter())
       {
         LinqMetaData meta = new LinqMetaData(adapter);
         var datas = (from x in meta.Table
           where x.DateCreated >= startDate && x.DateCreated <= endDate && x.ViaTo > 0 && !x.Cancelled
           group x by new { month = x.DateCreated.Value.Month } into g
           select new
           {
            MonthNr = g.Key,
            //MonthName = ?
            TotalMonthAmount = g.Sum(x => x.Amount)
            });
.....
       }

您可以使用此函数获取月份名称：

using System;

class Program
{
    static void Main()
    {
        DateTime now = DateTime.Now;
        //
        // Write the month integer and then the three-letter month.
        //
        Console.WriteLine(now.Month); //outputs 5
        Console.WriteLine(now.ToString("MMM")); //outputs May
    }
}

不，我只创建了DateCreated，它是DateTime类型。可能的重复项不，我只创建了DateCreated，它是DateTime类型。可能的重复项monthNumber是MonthNr吗？（就我而言）我相信这是g.KEYMONTHNUMBER在哪里是MonthNr？（就我而言）我相信是g.Key
